    Nissan is producing a motor using an electro-magnet rotor which eliminates the need for permanent magnets:


    The same as running an alternator as a motor, this is a brilliant solution as it also solves the problem of back-EMF that requires 'field weakening' in traditional motors. There is no free lunch as the rotor coils require power but the dynamic range of efficient power production is well worth it.

    does it reduce rare element usage?

    Yes. By orders of magnitude.

    i wonder if they are expensive motors to build. ariya is not an inexpensive car, for what you get

    I like the rational they used, reduce the supply chain issues and make highway driving energy efficient by not needing to waste battery capacity using field weakening. As said in the video, no one really cares about town energy consumption, plenty of recharge facilities in the city, not so much out on the freeways.
